Conveying device containing shape memory alloy

Abstract

A transport device (400) comprises a housing (410), an actuator (430), a drive (450) and a sealing element (470). The housing has a fluid inlet (411, 413) and a fluid outlet (413, 411). The actuator (430) comprises a magnetic shape-memory alloy, and the actuator (430) is arranged at least in sections in the housing (410). The actuator (430) can be deformed by the drive (450) in such a way that two cavities (635, 635′) for the fluid are formed in the actuator (430), which cavities can be moved by the drive (450) in order to transport the fluid in the cavities (635, 635′) from the fluid inlet (411, 113) to the fluid outlet (413, 411). The sealing element (470) has at least one recess (471, . . . ), and the sealing element (470) is arranged in the housing (410) in such a way that the cavities (635, 635′) are at least temporally in fluid communication via the recess (471, . . . ) during the transport of the fluid from the fluid inlet (411, 413) to the fluid outlet (413, 411).
